if it is such a great add on, one would imagine that Ford and GM engineers would come up with their own system. I have it on my 2020 and yes at times while I'm pulling it seems to work by hearing it adjusting other than that I personally can't tell the difference between the one that dosnt have it. But this is just my opinion. I'm glad to hear others love it.They do not, it’s a class exclusive for Ram.
